Bistatic and Multistatic Radar Systems [PDF]

Radioengineering, 2008
Radar systems, based on bistatic radar concept attracted a substantial attention in the recent years. Passive coherent location systems using \"transmitters of opportunity\" like radio or TV broadcasters, GSM base stations, satellite communication and ...

The flow structure behind vortex generators embedded in a decelerating turbulent boundary layer [PDF]

, 2009
The objective of the present work is to analyse the behaviour of a turbulent decelerating boundary layer under the effect of both passive and active jets vortex generators (VGs).

Specificity and coherence of body representations [PDF]

, 2009
Bodily illusions differently affect body representations underlying perception and action. We investigated whether this task dependence reflects two distinct dimensions of embodiment: the sense of agency and the sense of the body as a coherent whole.

WiFi-based PCL for monitoring private airfields [PDF]

, 2017
In this article, the potential exploitation of WiFi-based PCL systems is investigated with reference to a real-world civil application in which these sensors are expected to nicely complement the existing technologies adopted for monitoring purposes ...

Lagrangian Based Methods for Coherent Structure Detection [PDF]

, 2015
There has been a proliferation in the development of Lagrangian analytical methods for detecting coherent structures in fluid flow transport, yielding a variety of qualitatively different approaches. We present a review of four approaches and demonstrate

Lagrangian coherent structures in nonlinear dynamos [PDF]

, 2011
Turbulence and chaos play a fundamental role in stellar convective zones through the transportof particles, energy and momentum, and in fast dynamos, through the stretching, twisting and folding of magnetic flux tubes.

Extraction of coherent structures in a rotating turbulent flow experiment

, 2004
The discrete wavelet packet transform (DWPT) and discrete wavelet transform (DWT) are used to extract and study the dynamics of coherent structures in a turbulent rotating fluid.

2D localization with WiFi passive radar and device-based techniques: an analysis of target measurements accuracy [PDF]

, 2018
The aim of the work is to investigate the performance of two localization techniques based on WiFi signals: the WiFi-based passive radar and a device-based technique that exploits the measurement of angle of arrival (AoA) and time difference of arrival ...
